This refers to the difference of arrival time between primary waves and secondary waves.​

Sagot :

Answer:

S waves are indicated by an abrupt change in wave amplitude. In the seismogram below, we see that the S wave arrived at about 34 sec after the P wave arrived. This time difference is called the S-P interval and is the lag time between the P and S wave.
